摘要/Abstract

摘要： 针对容积式空气压缩机产品质量检验过程中缺乏完整的和系统的容积流量测量、不确定分析和试验方法的问题,基于ASME喷嘴容积流量测量法对容积式空气压缩机流量进行了测试方法研究。该方法可由空气压缩机性能参数试验获得大气压力、压缩机一级吸气温度、喷嘴上游气体温度以及喷嘴压差等主要参数,然后通过计算得到容积流量和不确定度。以某公司的DG22HA型、JG22HA型和LG22A型容积式空气压缩机为例进行ASME喷嘴法容积流量测试应用,得到其容积流量分别为3.37、3.33和3.43 m³/min,同时流量测量结果的不确定度分别为0.016、0.016和0.017。根据结果可知,该方法能够准确、简单和有效地获得容积式空气压缩机的容积流量,为空气压缩机生产部门对产品的性能检测和设计提供了参考。

Abstract: There were some prombles in the the products quality inspection process of the displacement air compressor,for instance the lack of volume flow measurement,uncertainty analysis and test method integrallty and systematically.Thus researched flow testing method for displacement air compressor based on the ASME nozzle flow measurement method,which can be used to caculate volume flow when the performace parameters such as the atmospheric pressure,the first grade suction temperature,the nozzle upstream gas temperature and the nozzle pressure difference et al,were gotten by performance tests.At the same time,the uncertainty of flow measurment results also can be obtained.Three types displacement air compressor of one compressor manufacturing company,ie DG22HA type,JG22HA type and LG22A type were taken as an example for application of the ASME nozzle flow measurement method.Their volume flows were 3.37,3.33 and 3.43 m³/min,and their uncertainties were 0.016,0.016 and 0.017 respectively.Results show that the method can accurately obtain the volume flow of compressor simply and effectively.It is useful for air compressor production department for product performance test and design.
